You can put this solution on YOUR website! I'll do the first four to get you started
a)
A ∩ B = Set of elements that BOTH sets A and B have in common
A ∩ B = {1, 2, 3} ∩ {3, 4, 5, 6}
A ∩ B = {3}
----------------
b)
A ∩ C = Set of elements that BOTH sets A and C have in common
A ∩ C = {1, 2, 3} ∩ {3, 5, 7}
A ∩ C = {3}
----------------
c)
A U C = Combination of the sets A and C (remove any duplicates)
A U C = {1, 2, 3} U {3, 5, 7}
A U C = {1,2,3,5,7}
----------------
d)
B U C = Combination of the sets B and C (remove any duplicates)
B U C = {3, 4, 5, 6} U {3, 5, 7}
B U C = {3,4,5,6,7}
